Title: Pulse laser device
Inventor: MURAKAMI YOUICHI
IPC: H01S3/0915
Filed: 1983-11-08
Abstract: PURPOSE:To maximize the inverted distribution of a laser active substance at all times by observing the luminous intensity waveform of a flash lamp and driving a Pockels cell at timing when the inverted distribution of the laser active substance is maximized. CONSTITUTION:The waveform of the luminous intensity of a flash lamp 4 is observed by a photodetector 15, and an output from the detector 15 is amplified by an amplifier 16. A differentiation circuit 17 obtains a signal in magnitude proportional to a change with time of an output signal from the amplifier 16, and an output from the differential circuit 17 reaches to zero at timing when the luminous intensity waveform of the lamp 4 is maximized. A zero value detecting circuit 18 generates a trigger signal at timing when the output from the circuit 17 reaches to zero, and a pulse generating circuit 11 receives the trigger signal and pulses are generated from the circuit 11. A high-voltage pulse generating circuit 12 drives a Pockels cell 7 by an output from the circuit 11. Consequently, the cell 7 is operated at timing when the inverted distribution of a laser active substance 5 is maximized at all times even when the waveform of the luminous intensity of the lamp 4 changes. Accordingly, a laser oscillator 1 can acquire the maximum output at all times.

Title: Recording disk reproducing device
Inventor: KOBAYASHI KOICHI
IPC: G11B19/20
Filed: 1989-08-11
Abstract: PURPOSE:To contrive miniaturization and reduction in weight of the subject device by changing the inclination of a disk by operating a space adjusting means and adjusting the distance between the disk and a pickup. CONSTITUTION:The distance between the disk 1 and the pickup is adjusted by changing the inclination (horizontality) of the disk 1 placed on a turntable 3 of a spindle motor 2 by moving vertically the height position of the other end of a bracket 14 by the space adjusting means 16. By this method, without providing a pickup height correcting mechanism on a pickup carriage 5, the pickup carriage 5 can be miniaturized and reduced in weight, and hence the relating structure and the whole device can thus be miniaturized and reduced in weight.

Title: Blade position detector
Inventor: NISHIDA TETSURO
IPC: B24B49/12
Filed: 1991-08-21
Abstract: PURPOSE:To position the tip of a blade so accurately in a noncontact state in response to a variation of wear in the blade. CONSTITUTION:A nozzle 56A is able to spray water and air to respective opposed surfaces 36A, 38A of two prisms 36 and 38. Accordingly, at the time of machining, it sprays water, forming a water screen over these opposed surfaces 36A, 38A of the prisms 36, 38, keeping off any sticking of chips being produced during the machining, and it sprays air at the time of detecting a position of a blade 54, through which waterdrops stuck to these opposed surfaces 36A, 38A of the prisms 36, 38 are eliminable. With this constitution, since a mist contained with chips to be produced during work machining is preventable from sticking to these opposed surfaces 36A, 38A of the prisms 36, 38, these surfaces 36A, 38A of the prisms 36, 38 are kept clean and, what is more, a light quantity to be conducted to a photodiode 23 can be kept constant.

Title: Facing process
Inventor: TOMIUCHI SHINICHI
IPC: B05D1/20
Filed: 1982-11-30
Abstract: PURPOSE:To form a pattern abound in variety on a building plate or the like, in a water-surface transfer method, by respectively changing solvents, etc. to change the states of coating materials diffused on the surface of water. CONSTITUTION:The amount of the first paint 4 to be diffused corresponding to a pattern to be formed is taken out from the first paint reservoir part 2 to the second one 4, where the second paint 6 is added to it. The first paint 4 and the second paint 6 are made at least completely immiscible with each other by the selection of solvents, etc. By opening the second gate 5 under this condition, the paints begin to diffuse into a linear or dotted shape on the surface 7 of water while mixing or harmonizing them with each other. Thus, an irregular pattern due to both of the paints is formed.
Patent JP-S6365585-A (JP)
Title: Optical reader
Inventor: HATANO YOICHI
IPC: G06K7/00
Filed: 1986-09-05
Abstract: PURPOSE:To decode a code having the different reflection factor of light, by receiving scan reflected light beams by two or more photodetectors so that a phase difference is generated, and also, converting them to electric signals, and comparing the levels of the electric signals having a phase difference after having amplified them by an amplifier, respectively. CONSTITUTION:By comparing the levels of electric signals from photodetectors having a phase difference, it becomes unnecessary to set a threshold level. A code can be decoded by replacing whether a code having the different reflection factor of light is long or short, with whether the time required from the intersection to the intersection of a waveform is long or short, by the waveform of a time delay caused by the phase difference, and since the threshold level is not set in advance, the wrong decoding of a code scarcely occurs. Also, by the reverse direction parallel connecting body of a diode, this reader is scarcely influenced by a disturbance light.

Concretely, by downwardly pulling the towing wire 41a, the rod 32a is upwardly towed, whereby a guide tube 31a is contracted, and a structural body is dilated. When the guide tube 31a is contracted, and the structural body is dilated, a distal end of the engagement part 35a of the rod 32a is passed through an upper distal end of the guide tube 31a, projected to the external of the guide tube 31a, and engaged with an upper distal end of the guide tube 31a. Whereby an dilation state of the intraluminal indwelling can be kept.

The channel 20 is made taper in order to reduce the undesired empty space in the channel 20. The undesired gas in the supply matter in the adsorbent bed is adsorbed by an adsorbent. Desiredgas (product gas) passes through an inside screen wall 18 to flow out to enter an annular inside product gas flow channel 24. The product gas flows downwardly from the channel 24 and subsequently passes through a product outlet conduit 42 to rise to flow out of the top part of a container 10.

Title: Braking hydraulic pressure controlling method for automobile hydraulic controller

IPC: B60T8/172
Filed: 1986-09-08
Abstract: PURPOSE:To prevent unbalance between right and left of rear-wheel braking force on the basis of a speed difference from occurring, by constituting control over braking hydraulic pressure on rear wheels so as to be performed on the basis of wheel speed in a lower side of front wheels at the time of operation of a differential limiting device. CONSTITUTION:At the time of operation of a differential limiting device, control over braking hydraulic pressure to braking devices 5a and 6a for rear wheels 5 and 6 is constituted so as to be performed on the basis of a wheel speed signal in a lower side in wheel speed signals emitted by wheel speed sensors 3b and 4b for front wheels 3 and 4. Therefore, timing of decompression in the braking hydraulic pressure for these rear wheels 5 and 6 is quickened and thereby occurrence of the speed difference based on a difference in a surface friction factor between symmetrical rear wheels 5 and 6 is reducible, so that intershafting transfer of friction torque to be produced by the speed difference is held down to the minimum, whereby the occurrence of unbalance of surface transfer braking force of these symmetrical rear wheels 5 and 6 is reducible. With this constitution, stability in the yaw direction of a vehicle is improvable.
